Abstract
A pretreatment fluid includes an effective amount of a fluorinated surfactant and a vehicle. The fluorinated surfactant is selected from at least one non-ionic fluorinated surfactant, at least one ionic fluorinated surfactant, and combinations thereof. The effective amount is selected based upon: a system in which the pretreatment fluid is used, an ink composition used in the system, system pretreatment time, pretreatment vehicle components, or combinations thereof.

- wherein Q1 and Q2 are independently selected from H and SO3−W+, wherein W is selected from NH4+, Li+, Na+, and K+, wherein R2 and R4 are independently selected from H and OH, wherein R1, and R5 are each O(CH2)m—(CF2)n—CF3, wherein m ranges from 1 to 3 and n ranges from 0 to 3, wherein R3 is
- wherein L ranges from 1 to 4, and wherein x ranges from 1 to 10, y ranges from 1 to 30, and z ranges from 1 to 10;
- a vehicle;
- and;
- optionally at least one non-fluorinated surfactant;
- and
- optionally ethylene-diamine-tetra-acetic acid (EDTA);
- wherein the effective amount is selected based upon:
- a system in which the pretreatment fluid is used, an ink composition used in the system, system pretreatment time, pretreatment vehicle components, or combinations thereof, and wherein the effective amount of the fluorinated surfactant includes the at least one non-ionic fluorinated surfactant and the at least one ionic fluorinated surfactant present in a weight ratio ranging from about 1:200 to about 200:1.
